Heretofore various arrangements have been.

provided for adjusting windows vertically. The

conventional double hung window is an example of a slidable sash which carries panes of glass. Glass panes have also heretofore been mounted for sliding movement laterally within a fixed frame, thus in contrast "to a slidable sash. It ha's'also been proposed to provide for the vertical adjustment of glass panes which are held by metal spring devices adapted to engage the lateral edges of the panes. This latter form of construction has faults by reason of the engagement of metal with glass, a'combination which is both. noisy and destructive to both the metal and the glass. Such an arrangement is peculiarly damaging to the edges of laminated glass panes and is entirely unsuitable when a double or vacuum-type of pane is used. The present invention is a departure from the abovementioned constructions and avoids the structural troubles, wear and tear and noise inherent to e that type of pane mounting in which the pane is frictionally held by a metal spring in 'engagement with the edge of the pane.

One of the features of the present'invention is the use of a portion of the window sash to'serve as an adjustable clamping strip whereby pressure is brought against the face'of the pane ad-' jacent its marginal edge. This construction makes it possible for the window sash to have the appearance and general'contour of a'conventional sash; however, the clamping strip por- 'tion whichjextends vertically is adjustable with respect to the main portion of the sash and with respect tothe pane against which it is adapted to exert pressure.

.,im'p'roved construction also provides an advantage by reason of the fact that the pres-,-

sure is exerted against the face of the pane ascontrasted to the edge of it.) Obviously the pane should be smooth, whereas quite frequently the edges of glass panes are not dressed down to very exact smoothness. Thus the application of retaining pressure against a smooth surface reduces to aminimum both wear and tear and makes it possible for the pane to, be adjusted vertically freely and evenly.

In fconjunction with the adjustable vertical strip to assist holding the slidable pane, the

construction also includes the use of a felt or cloth friction strip to embrace the lateral marginal'edges of the slidable glass pane. The sash is provided with opposed grooves in which the pane is adapted to slide vertically. Preferably the grooves extend the height of two panes and the upper'pane may be fixed. The friction strip is located in the grooves and is adaptedto fit in between the edge of the glass pane and the walls and are illustrated in the accompanying drawings, in which:

Fig. 1 is an elevational view of the face of a window sash four panes in height'and of which the bottom panes and the panes next to the top are slidably mounted;

Fig. 2 is a sectional view taken 'on the line 2-2 of Fig. 1 looking in the direction ofthe arrows;

Fig. 3 is a sectional view taken on the line 33 of Fig. 1, looking in the direction of the arrows;

Fig. 4 is an enlarged fragmentary sectional view taken on the line 4 -,4 of Fig. 1; and

Fig.5 is an enlarged horizonta1 sectional view of one form of the structure, broken away at the center, showing the front or inner face of a window sash used as the strip for clamping the slidable pane.

Referring in detail. to the several figures of the I at least two paneshigh'. With this characteristic construction 'as'a criterion, Fig. 1' illustrates a Such a construcwindow sash four panes high, in which the lowermost pane and the pane third from the bottom are slidably mounted. According to Fig. l, the right hand side rail is indicated at l, and 2 is the left hand side rail of the sash. 3 is the top rail and t is the bottom rail. Those rails may be secured together in any convenient manner sufficient to provide the inherent strength essential for a window sash or door. is a conventional meeting rail which-- serves to strengthen thes sash framework formed by the rails I; 2 3 and l. The meeting rail 5 also serves to limit the lower movement of the panes next above it and to sep-. arate those movable panes from thQ flXQd pQlll next beneath the rail 5. i

Cross bars 6 are shown at the bottom- Ogtbfig fixed panes and at the top of the slidable panes, as will be explained.

The second groove, located inwardly of the groove for the fixed pane, is more correctly a substantially right angled notch in the edge portion of the rail portion I5. The adjacent-face of the side rail portions 1 and 2 completes the side walls of this second groove, as will be obvious by reference to Figs. 3 and 5.

to the muntin core l and its outer facing strip H. The outer facing strip I1 is conventional and may be used to assist in the weatherproofing and exterior finish of the sash.

In Fig. 2, there is illustrated a suitable form of construction for .the meeting rail, the inner decorative strip of which is indicated at 5. The heavier portion of the meeting rail is indicated at and 5 receives the upper edge portion of the fixed pane 8 and also receives the upper slidable pane 9 when it is in the lowered position.

Also'in Fig. 2 is iJlustrated, in cross section, a suitable construction for the cross bar which has an inner facing strip 6 and an intermediate or outer portion 6 which fills the space between the fixed pane 8 and the slidable pane 9 and likewise may support the lower end of the fixed pane 8. However, inasmuch as the fixed pane 8 is preferably fixedly secured, it may be held in place solely by putty.

It will be obvious that the grooves for the reception of the slidable pane 9 should be substantially double the length of the pane whereby a track is provided for the slidable adjustment of the pane. v From the foregoing, it will be clear that this improvement provides a construction whereby a pane of glass or its equivalent, free from any binding strip or protective edge carried by the pane, is mounted for vertical adjustment and that the regulation of the pressure at the marginal faces of the pane may be performed by adjustment of vertical strips which have the appearance of being an inherent and normal part of a conventional sash.

It will also be clear that the adjusting means, namely, the screws l2, l3 and I4 are readily accessible at the face of the window and are not obscured.

It will be understood from the foregoing that th window sash described has side edges and opposed faces which latter have directly visible display portions, characteristic of conventional window sash, and in which the adjustable'tensioning screws are located, as indicated at l2, I3 and I4.
